Frequently asked questions

Office 365 Business Premium supports a maximum of 300 users. If you have more than 300 users or think you will soon, take a look at our other plan options.

What forms of payment can I use?

You can pay with all major credit cards, and your subscription amount will appear on your credit card statement. You have the option to receive an invoice and, depending on your choice of services, you will be billed monthly or annually. You receive an email message when your invoice is ready to be viewed and, if a purchase order (PO) number is entered when you buy your subscription, that number is included in your invoice.

What payment options are available? Can I pay monthly or annually?

You can choose monthly commitment payment or annual commitment payment for Office 365 Business Premium.

Monthly commitment payment: You pay month by month, and you can cancel at any time.

Annual commitment payment: You sign up for a one-year subscription, but you can choose to pay month to month or pay for the entire year at the time you sign up. There is a discount for using this payment option.

I’m running Windows Vista or Windows XP. Will I have any limitations?

Office 365 Business Premium supports Windows Vista and Windows XP for most web-based functionality. However, it does not support the download and use of the latest version of Office software, and you cannot substitute Office 2010 for the latest version. You can connect your existing Office 2010 or Office 2007 software to the Office 365 service, but if you are running Windows Vista or Windows XP, you cannot install Office 365 Business Premium software, and you cannot replace Office 365 Business Premium software with a download of Office 2010.

Can I cancel my subscription at any time?

You can cancel your subscription at any time. Office 365 Business Premium subscriptions are available for monthly commitment payment or annual commitment payment. For monthly commitment subscriptions, there is no penalty for canceling your contract at any time. Annual commitment subscriptions that are paid month to month may incur some penalties if canceled early. Annual commitment subscriptions that are paid up front do not receive a refund if canceled prior to the full contract period. Read the complete Microsoft Online Subscription Agreement.

What happens to my data if I cancel my subscription?

Your data is yours. If you decide to cancel your Office 365 subscription, you can download your data—for example, your email and documents on team sites—and save it to another location. You should save your data before you cancel. After you cancel your subscription, data associated with your Office 365 account will be available to your administrator(s) in a limited function account for 90 days.

Can I switch to other Office 365 plans?

Yes. If you need to upgrade, you can transition your account to a different plan. For example, you can upgrade from an Office 365 Business plan to an Office 365 Enterprise plan.

In most cases, you can use the Switch plans wizard in your Admin center to upgrade your plan. If your subscription has more than 300 users or if you used a prepaid card to purchase your plan, the Switch plans wizard is not available. Plans that are not eligible for the Switch plans wizard can be upgraded manually. Learn more about upgrading Office 365 plans.

NOTE: When you upgrade your account, your domain name is transferred to your new account, whether you brought your own domain name to the Office 365 account or you set up a domain name with Office 365.

Can I mix and match different Office 365 plans?

Yes, you can mix and match Office 365 plans. Please note that there are some license limitations at the plan level. The Office 365 Business, Business Essentials, and Business Premium plans each have a limit of 300 users, while the Enterprise plans are for an unlimited number of users. For example, you can purchase 300 Business Premium seats, 300 Business Essentials seats, and 500 Enterprise E3 seats on a single tenant.

Is Internet access required for Office 365?

Internet access is required to install and activate all Office 365 plans and to manage your subscription account. Internet connectivity is also required to access Office 365 cloud productivity services, including email, conferencing, IT management, and other services.

Many Office 365 plans also include the desktop version of Office, for example, Office 365 Business Premium and Office 365 Enterprise E3. One of the benefits of having the desktop version of Office applications is that you can work offline and have the confidence that the next time you connect to the Internet all your work will automatically sync, so you never have to worry about your documents being up to date. Your desktop version of Office is also automatically kept up to date and upgraded when you connect to the Internet, so you always have the latest tools to help you work. Compare Office 365 plans.

What is the cloud?

“The cloud" is a friendly way of describing web-based computing services that are hosted outside of your organization. When you use cloud-based services, your IT infrastructure resides off your property (off-premises), and is maintained by a third party (hosted), instead of residing on a server at your home or business (on-premises) that you maintain. With Office 365, for example, information storage, computation, and software are located and managed remotely on servers owned by Microsoft. Many services you use every day are a part of the cloud—everything from web-based email to mobile banking and online photo storage. Because this infrastructure is located online or “in the cloud,” you can access it virtually anywhere, from a desktop, PC or Mac, laptop, tablet, smartphone, or other device with an Internet connection.

What happened to the Office 365 Small Business Premium plan? What happened to the Office 365 Midsize Business plan?

The Office 365 Small Business Premium and Office 365 Midsize Business plans have been replaced by one new plan, called “Office 365 Business Premium.” Office 365 Business Premium combines the best features and services into one plan, with a maximum of 300 users.
